The joint solution builds on Silver Spring and Smarter Grid Solutions'
existing engagement at the successful Flexible Plug and Play project,
delivered to client UK Power Networks, the distribution network operator
for London, and the South East and the East of England. In the Flexible
Plug and Play (FPP) project, Silver Spring's networking technology
connects an array of distribution equipment across a deployment of
intermittent wind and solar resources in Cambridgeshire, UK. This
deployment also successfully demonstrated the use of the IEC (News - Alert) 61850
protocol across a radio mesh field area network.

At the core of the FPP project, Smarter Grid Solutions' Active Network
Management technology monitors the electricity grid using data provided
by Silver Spring's field area network. The system autonomously
calculates the available capacity of the grid and issues real-time
control instructions to participating DERs. The project has delivered
significant savings to UK Power Networks on the capital expenditures
otherwise required to reinforce the project area.

"Utilities have enormous challenges in maintaining reliability while
integrating new sources of generation using traditional network
reinforcement and reliability schemes," said Eric Dresselhuys, Executive
Vice President of Global Development, Silver Spring Networks. "By
offering this proven solution to our customers, Silver Spring and
Smarter Grid Solutions are enabling utilities, and ultimately the end
consumer, to save money and enjoy the benefits of a cleaner, more
reliable and more efficient energy grid."

"In the course of delivering several successful projects, we have found
that many utilities were making long-term grid reliability decisions
without fully integrating their strategy for the underlying
communications fabric," said Gerry Docherty, Chief Executive, Smarter
Grid Solutions. "In order to run the next generation of distributed,
intelligent applications, we need reliable, responsive communications
infrastructure that doesn't risk the funamental utility business case.
Silver Spring's proven IPv6 networking platform makes them the ideal
partner to ensure these criteria are met."

To commemorate the new Silver Spring and Smarter Grid Solutions teaming
agreement, the Rt Hon Alex Salmond MSP, First Minister of Scotland,
joined executives from both companies at a signing ceremony that also
celebrated the official opening of Smarter Grid Solutions' North
American headquarters in New York City.
